RIBBON MEl'JHANISM FOR FRONT-STRIICE TYPE-WRITING MACHINES.

- Specification. of Letters Patent.

Patented March 3, 1903.

Application filed March 16. 1907- Serial No. 362.733-

To all whom it may concern:

,Be it known that 1, WILLIAM R. Fox, a citizen of the United States, residing at Grand Rapids, in the county of Kent, State of Michigan, have invented certain new and useful Improvements in the Ribbon Mechanism for FrontStrike Type-Writing Machines, of which the following is a specification.

This invention relates to improvements .in mechanisms and devices for front strike typewriting machines.

The objects of the invention are to provide an improved mechanism and means for controlling the ribbon vibrator, so that the full width of the'ribbon may be utilized and also so that a party-colored ribbon may be utilized, and so that the ribbon vibrator can be depressed and not swing the ribbon to the printing position when it is desired to make stencils, as for rnimeograph work.

Other objects relate to improvements in the arrangement of the parts and particularly to the construction of the improved ribbon guide.

Objects pertaining to details ofconstruction'and mechanism'will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a detail sectional view of the portion of a typewriting machine embodying the features of my invention, taken on a line 1-1 of Fig. 2; Fig. 2 is a detail sectional elevation view of the front portions of a typewritin machine,taken on a line corres on ing'to line 2-2 of Fig. 1, showing the re ation of the ribbon vibrator and of the various mechanisms for securing the operation, control 'and adjustment of the ribbon, referred to, the oscillator for the ribbon vibrator being adjusted for utilizing the full width of the ribbon; Fig.3 is a similar sectional view to that appearing in Fig. 2, showing the rib bon oscillator out of gear and showing the mechanism adjusted for the use of a partycolored ribbon; Fig. 4 'is' a detail sectionalview, taken one line corresponding to line 4 4 of Fig. 3, showmgthe shifting means for" using the party-colored ribbon; Fig. :5 isa The ri lan view of the ribbon vibrator, the position i of the ribbon being indicated by the dotted line; Fig. 6 shows the link connection and automatic lock of the adjustin mechanism for utilizing a arty-colored rib stop means w 'ch revents its interferin with the ribbon osci lator; Fig. 7 1s a detai view of the yielding connection between the actuating lever and the ribbon vibrator; and

Fig. 8 shows the details of the connection on, and the between the lever arm-37 and the yielding arm 32.

-In the drawing, taken looking in the direction of the little arrows atthe ends of the section lines, and similarnumerals of reference refer to similar parts throughout the several views. Referring to the numbered parts of the drawing, the frame 1 is of the usual form for use in the Fox ty ewriter. The ribbon spools 3 are supporte on suitable transverse shafts 2-2 and The invention here not means for driving the ri same is not illustrated.

Guide spools 6-6, supported on brackets pertaining to the hon spools, the

5-5, are at each side of the machine for receivin and guiding the typewriter ribbon.

bon is deflected and twisted at substantially right angles on its axis and inserted into the ribbon vibrator 40. The rib- ,bon guide 40 is formed of sheet metal integral with the arms 39-39, being turned downwardly therefrom, and the arms are secured to the rock-shaft 38. The rock shaft 38 is-suppor. on suitable bearings, preferably pointer screws, towards the front of the machine.

The ribbon guide 40 is slotted to form the intermediate upwardly projecting fingers 40, separated from each other at the printing point, over which the ribbon is looped. The ribbon is retained between these fingers and the body of the vibrator. The fingers, as before remarked, are separated sufiiciently to permit the stroke of the t pe between them. The ribbon is arrange underneath the angle of the arms 39, at theirpoint of connection to the guide 40, and is prevented from upward displacement by that means.

A downwardly depending lever arm 37 "is secured to the rock shaft 38, and is the lever arm by which the ribbon vibrator is actuated.

are operated by any usual or preferred mechanism for the purpose.

the sectional views are stop means for controlling the movements of the vibrator when it is desired to use a partythe movements of the link 9 on the ivot on the arm 7. An adjustable stop 14 is on the rear end of the link 9, the same being adjustable by suitable lock nuts. A flange 11 is turned at right angles to the link 9 to receive this ad'ustable stop 14. V

,On a roc shaft 12, controlled by the. knurled head 53, is an arm 12 which carries the pin 13, acting in the slot 13 of the link 9. A'notch is on the edge of the arm 12, and a, yielding spring catch 51 is secured to the typewriter frame above for supporting this arm 12 yielding in its elevated position.

The stop 14- on the link 9 is arranged to' swing into the path of motion of the lever arm 37 as seen in Fig. 2. When the-device is in the position indicated in Fig. 2, it will be noted that, as the spool 3 revolves, the 'face cam 4 will act upon the shoe 8, and the stop 14 will be moved back and forth as a consequence, depending on the position of the cam 4. It moves freely because the link 9 is free to move over the pin 13, the-slot 13 permitting the movement. This moves the stop 14;,back and forth and consequently controls and varies the. movements of the lever arm 37 thereby permitting the ribbon vibrator to move difier'ent distances as the ribbon spool rotates thereby secures the with its face cam 4 and oscillation of the ribbon vibrator which oscillates the'ribbon and util-' izes the full width thereof.

As before remarked, the lower end of the lever arm 37 is curved, the extreme lower end 37 being ofiset from, the'p'ortion' of this'lever a little above the same.

When a party-colored ribbon is used, one edge is black and the otheris red, 'or some. other color, as may be desired; and it is obvious that by controlling the movements of .the vibrator 40, the upper part or edge or" the-lower part or edge of the ribbon may be utilized. The party-colored ribbon is indicated in Fig. 1. A stop .17 is provided which is ad ustable up and down onthe plate 15 to permit'the main part of the lever arm 37 or its offset part 37, to contact with the 'sto thus controlling the height to yivhich the ribbon will be raised and, by so om The %top 17 is carried on the swinging plate 15, the motion up and down of which is limited b the pin' 18 on the frame, extending'into t 0 slot 18 on the plate 15. A link,

.when the key 27 is depressed.

using either the upper or lower part.

20 dependsfrom this oscillating plate 18 and, I

is secured to the levers 27 and 29 by a pivot 31 common to both levers. fulcrumed at 28 at its rear end and is provided at its front end with a key button so that an operator, in depressing the key 27,

The lever 27 is will bring the plate 15 down to the limit of" its motion by the connection. The lever 29 is fulcrumed at 30, at pivot 31 in front of r the fulcrum, and connects to the lever 20 by the pivot 31 back of its fulcrum 30, and is provided with a key button at its front end so that depressing the front end of the lever 29 throws the link 20 upwards and elevates, the plate15; The plate 15 is locked automatically in position by the spring 46, which embraces the pin 18 and is connected to the pivot pin 20' whichconnects the link 20 to the plate 15, and, as this is thrown up past the center or down past the center, as the case may be, by the operation of the levers, it will be seen that the same is held normally inposition. On the upper rear corner of the'plate 15 is a stop 15 which, when the plate 15 is eleva'ted, contacts withthe arm 12 and pre vents the ribbon oscillator being thrown into position when the lever 29 is depressed. By ribbon oscillatoris meant the parts consisting of the arms 39 and downwardly bent portion 40 supported on a suitable rock shaft38 arranged in the front part of the machine. This insures the proper relation of these parts, so that the full oscillation of the ribbon is-secured when the ribbon oscil-- lator is thrown into position, and the ribbon oscillator. can only be thrown into position ribbon oscillator is in gear, the arm 12 is thrown down to the position indicated in Fig. 2, and'it engages the stop 15 and insures that the party-colored mechanism cannot be operated by the ribbon oscillator when in use. v I

When it is desired to depress the ribbon vibrator, for the purpose of making stenoils, 1 provide a lever 41, controlled by the plunger 43, terminating in a .button 43 at the front of the machine. A spring 44 holds this plunger normally upward, so that the notches thereon engage the catch 45. Sim

When the 'ply pushing this button swings. the lower end ofthe lever 40 inward portion out against the lever arm 37, thus. holding the ribbon vibrator in the depressed position. When it is desired to release the ribbon vibrator, the button 43 is merely and the upper ressed, when the spring 44, owing to its suitable spring umechamsm. A rock shaft Bette is 24 is supported by suitable pivoted'brackets 25 on the'comm'on cross-bar 26 of the maated by the movements of the levers 23,

which rock the rock shaft 24. A plate 32 is parallel therewith and extends upwardly therefrom and is slotted andv receives the lever arm 37loosely therein.

32 are a pair of pins-34 34 (see Fig. 7

which extend through apertures in the plate 33. A central pin 35 extends through the same and is provided with a suitable nut at the end, and a coiled spring 36 acts between this nut and the plate 33 to hold the said late 32 yieldingly in p osition,-so that the evers or arms 23 can operate a full stroke, and are thus provided with a yielding con nection to the lever arm 37 on the rock shaft '38 which actuates the ribbon vibrator or oscillator. The tension of this device is easily adjusted by the nut 353referredto. It will thus be seen that the levers 23 can be fully depressed independent of the armj32,

which yields and, consequently, the move-' ment of the connected parts is readily controlled by the stop means.

Having thus 'described my invention,
